Description

Charcoal vessel

The present invention relates to a charcoal container prepared by adding a reinforced resin to the charcoal powder, and more specifically, to a charcoal container cast by adding 30 parts by weight of polyester and 10 parts by weight of talc to 100 parts by weight of the charcoal powder.

Oak charcoal is divided into white charcoal and gum charcoal according to its properties. White charcoal and gum charcoal differ in terms of carbon, oxygen, hydrogen, ash, and other components, such as hardness, calorific value, heat sustainability, and thermal power. Gum coal is produced at 400-700 ° C, and white coal is produced at high temperatures of 100 ° C or higher.

White charcoal is characterized by its high thermal power, long lasting, and fine pores, which have strong adsorptive power. Charcoal white charcoal in Korea is particularly excellent and has been used for a long time as a charcoal roast and fuel. The properties of the sand are hard and give a metallic sound when beaten. Compared to white coal, gum is softer and softer to ignite, and it is less burned and burned, so it is used more for smelting and forging than for cooking.

Wood materials of charcoal are oak, prunus oak, oak, chestnut, larch, pine, cedar, cypress, bamboo, chaff, palm bark, plum, pine, mulberry, etc. There are industrial, environmental improvement, health life, crafts and arts. Depending on the progress of carbonization of charcoal, low-temperature charcoal is carbonized charcoal at 400-500 ℃, charcoal, flat coal and mesophilic charcoal at 600-700 ℃. (Black charcoal) and high temperature charcoal are white charcoal carbonized at around 1000 degreeC.

Solid wood has cellulose, hemicellulose, and lignin, and is composed of elements such as carbon and hydrogen. When heated in an oxygen-free or low-oxygen environment, the wood is decomposed rapidly at around 280 ° C. Gases such as hydrogen and hydrocarbons are generated, and the wood gradually turns into amorphous carbon, which is rich in carbon and irregular in crystals.

When it is heated further to 650 ~ 700 ℃, oxygen or hydrogen decreases gradually and surface properties start to change significantly. In the solid state, the carbon content is 50, but when the carbonization temperature reaches 400 ° C, the carbon content is over 89 at 72 and 600 ° C and over 95 at 1000 ° C.

When the cross section of the char is magnified under a microscope, microns of micropores are formed inside the char. The surface area of 1 g of charcoal is about 300 m 2.

In addition, charcoal has many beneficial properties to the human body, such as abrasive, adsorptive, electromagnetic wave blocking.

Recently, various methods of utilizing charcoal for environmental preservation, agriculture, forestry and fisheries, rehabilitation, and food processing have been developed using the properties of the charcoal. If you look at some of these,

1) Purification

The adsorption capacity of charcoal is used to purify water for living water, rivers and lakes.

2) Use for agriculture, forestry and fisheries

Currently, charcoal and wood vinegar are used for horticulture, rice fields and fields, and for soil improvement and compost production in the cultivation of vegetables, fruit trees and tea.

3) Application to housing materials

By using the excellent moisturizing effect of charcoal, products such as residential environment moisturizer, wallpaper, floorboard, etc. are produced, and by-products of charcoal are utilized a lot.

4) Use for household goods

It is widely used as a deodorant for purifiers, refrigerators and shoeboxes, and for indoor cleansing. It is also sold as health products such as bed pads, pillows, and cushions.

On the other hand, far infrared rays were discovered by the German scientist Hussel in the 18th century and started to be used in the medical treatment of diseases from 1876, and thermal cancer treatment devices have been developed and used in the clinic in Korea. Far infrared rays are called life-growing rays and emit 3.6 to 16 microns of long-wave heat energy. This heat energy penetrates up to 40mm in the skin and expands the capillaries of the human body through the warming of the body, which facilitates blood circulation and circulates the substances of the human body. These rays are emitted from all matter on Earth, but charcoal, loess, stones and ceramics have high emissivity. Far infrared rays are the energy of life that changes the molecular structure of water. When char is put into water, the amount of oxygen increases and water rarely deteriorates.

The charcoal also has the effect of removing odors. It suppresses the occurrence of antiseptic and decaying bacteria, eliminating the source of odor and adsorbing odor.

Despite such various effects beneficial to the human body, such as far-infrared emission, conventional charcoal-containing products, such as jangpan, wallpaper, including charcoal, have a very low charcoal content, and thus it is difficult to achieve the beneficial effect of charcoal.

Korean Patent Laid-Open No. 2000-0012409 discloses a plastic container containing bamboo charcoal injection molded by adding 0.5 to 1.5 parts by weight of bamboo charcoal powder and 0.3 to 0.8 parts by weight of titanium oxide to 100 parts by weight of a plastic raw material.

However, the plastic container containing the bamboo charcoal is hard to expect the beneficial effect of the charcoal because the content of bamboo charcoal powder is only 0.5 to 1.5 parts by weight. In other words, in the deodorization test disclosed in FIG. 4, the deodorization rate of the plastic container containing the bamboo charcoal is about 30 to 35, which shows only a much reduced effect than the deodorizing ability of the charcoal itself. In addition, because it contains a small amount of charcoal powder, the amount of far-infrared rays emitted is also weak.

Accordingly, it is an object of the present invention to solve the above problems and to increase the content of charcoal as a main raw material and to provide a container capable of long-term preservation management of plants or food.

In order to achieve the above object, the present invention provides a charcoal container cast and molded by adding and mixing 20 to 50 parts by weight of an unsaturated polyester resin to 100 parts by weight of white charcoal powder.

In addition, the present invention adds and mixes 20 to 50 parts by weight of unsaturated polyester resin and 5 to 10 parts by weight of inorganic filler to 100 parts by weight of white charcoal powder to provide a cast and molded charcoal container.

The charcoal powder used in the present invention preferably has a particle size of 200 to 300 mesh, and the charcoal powder is more preferably made of oak charcoal. It is preferable that unsaturated polyester reinforcement water support charge is 20-50 weight part with respect to 100 weight part of white coal powder. When the unsaturated polyester reinforced water support material is less than 20 parts by weight, there is a disadvantage in that the molding is not good, and when it exceeds 50 parts by weight, there is a problem in that the deodorizing effect is lowered.

In addition, in the configuration of the present invention, by adding an inorganic filler such as talc to 15 parts by weight or less relative to the weight of the charcoal powder, the strength of the charcoal container can be further increased. When the added inorganic filler exceeds 15 parts by weight, not only the surface is not molded smoothly during molding but also there is a problem in that the production cost increases.

The present invention is characterized by manufacturing a container utilizing the high hard and high strength properties of the charcoal as it is, the charcoal container is manufactured by powdering the charcoal, in particular oak charcoal charcoal as a main raw material, but by injection molding rather than injection molding The original physical properties can be expressed.

Charcoal container of the present invention can be produced in a pot, vase, accompaniment, food container.

Hereinafter, the configuration of the present invention will be described in more detail with reference to the following examples. However, the scope of the present invention is not limited to the scope of the following examples.
